A cold fog generator will help make the fight against bacteria and insects effective. This device is designed for industrial and household disinfection, including in the presence of animals. How to choose a unit, what are its advantages over other means of struggle, are there any contraindications? To understand all the nuances, information about the device and the principle of operation, as well as advice and feedback from specialists and users, will help.

Operating principle

The cold mist generator differs from the conventional atomizer in its high efficiency. Bed bugs often hide in small crevices in floors and walls, in furniture niches, in suspended ceilings and other shelters that a person may not even know about. A special device ensures the penetration of the insecticide into hard-to-reach places, which cannot be done manually.

The essence of processing is as follows:

  1. The switched on generator releases jets of gas containing the smallest particles of a substance destructive to bedbugs. Vapors of the drug spread throughout all corners of the apartment, penetrate into cracks and holes in which insects like to hide.
  2. The insecticide gradually settles on all horizontal surfaces, as well as on insect bodies. A certain amount of the drug is inhaled by bedbugs, which causes damage to the nervous system, paralysis and death of parasites. If the bugs have not inhaled a sufficient amount of poison, it enters their body through the chitinous integument while moving on the treated surfaces and the insects die a little later.
  3. As a rule, the action of the remedy lasts for several weeks. This allows you to destroy individuals hatched from eggs that the bugs managed to lay before death..

Important! Cold fog is intended for the treatment of residential premises, as well as public institutions that occupy a small area. If it is necessary to carry out pest control on an industrial scale, in the area adjacent to the building or in a warehouse, this method will be ineffective.

Review of popular models

SM Bure. A new generation Korean device designed for a volume of 2.5 to 4.5 liters. Works with all types of pesticides, disinfectants, air fresheners, antibiotics, etc. The design is lightweight, easy to handle and move.

Longray 2680 A. China-made ultra-low fog generator. Designed for various types of fluids, both water and oil based. Has proven itself well when working in:

  • household premises;
  • in public places;
  • industrial use;
  • agriculture;
  • for public health.

Forms an almost invisible suspension, which improves its spread over the cultivated area. The volume of the tank is 6 liters, and the weight of the unit is 4.20 kg. The body is plastic, resistant to chemicals.

BURE - W2. A cordless, compact generator powered by a lithium-ion battery. The body is made of stainless steel, the total weight is 4.3 kg. It works with a minimum liquid consumption, there is an option to control the pump power.

A cold fog generator is able to cope with such a problem as insects, as well as disinfect a wide variety of premises. Such a device can be used both for domestic and industrial purposes. To choose the optimal model, you need to understand what type of processing is required, as well as what the area of ​​the room is. Based on this, you can choose a model, focusing on the parameter of the fluid flow rate.

Cold Mist Insecticides

From what drug is poured into the generator, it depends on how many days the bugs will die. Most often, insects are poisoned with such insecticides:

  1. Sinuzan - causes intoxication when it enters the intestines. Bedbugs die a few hours after contact with the drug. For processing, a 5% aqueous emulsion is used at the rate of 50 ml per 1 m2.
  2. GET - a product that is safe for people and pets. The death of insects occurs in 1-3 days.
  3. Xulat - a complex preparation, which includes three active components. Due to this, the bugs do not develop immunity to the poison. According to the manufacturer, all ingredients are enclosed in special microcapsules, which excludes their inhalation by humans. For processing, the substance is dissolved in water. The effect becomes noticeable after a few hours, but it must be taken into account that Xulat does not act on bedbug eggs, so the procedure will need to be repeated.

How do ultrasound models work?

To understand the features of the operation of such devices, it is important to determine two components of the workflow - this is the device directly generating ultrasound and the working environment. The first component acts on the working fluid medium by means of oscillatory waves (ultrasound) at frequencies sufficient to break the surface layer into small elements. In the process of operation, the aqueous medium is called sounded - at the moment, the ultrasonic fog generator performs the following operations on it:

  • Impact on the surface.
  • Increase of the surface of interaction of sound waves with liquid.
  • Dispersion. Scattering of liquid particles against the background of fine grinding.
  • Emulsification. Generation of emulsions.

It is not always necessary to complete a complete cycle of the described operations. Moreover, not every generator can in principle carry out, for example, dispersion and emulsification. Specific modes of operation with the list of operations are set by the user himself.

Cold Mist Generator Brands

Professional insecticide sprays are designed for large areas. They can only be used by employees of the pest control service.

The following generator models are suitable for disinsecting rooms and other small rooms:

  1. BURE SM В100 - distributes insecticide particles ranging in size from 10 to 50 microns. With the help of a powerful air stream, the substance is sprayed at a distance of up to 10 meters. The generator weighs 3.7 kg and can handle a room up to 100 m2 in just 1.5 minutes.
  2. DH-50 - equipped with a five-liter tank into which the insecticide solution is poured. The power of the device is 1.25 kW, the aerosol jet covers a distance of up to 10 m.
  3. AN-GAE Fog 4.5 - produces particles of 5-20 microns in size. The weight of the generator is 2.2 kg, the insecticide is sprayed on 5-10 m. It can be used not only for the destruction of parasites, but also for disinfection.

How does the device work?

The generator provides atomization of preparations, which, when colliding with the air flow supplied by the compressor, break up into a fine aerosol suspension resembling fog in consistency. This processing method is called "cold" because liquids are not heated during processing, in which they are converted into steam, but are sprayed at normal temperature.

This principle of operation is typical for aerosol generators, and disk or ultrasonic equipment operates in a slightly different way.

How to prepare a room for processing

Before using cold fog, it is necessary to carefully prepare the apartment for processing so that insects cannot hide. During cleaning, you need to do the following:

  • pack food products hermetically;
  • move cabinets, beds, armchairs, sofas away from the walls;
  • lift pillows and mattresses from furniture;
  • hide clothes in vacuum bags;
  • remove posters and paintings from the walls;
  • do wet cleaning, wipe off dust from all surfaces.

If the house has a basement, all rubbish must be removed from it. It is pointless to process a cluttered room, insecticides must penetrate into every corner.

Attention! Before packing, you need to make sure that they are free of parasites and their eggs. Otherwise, there will be no benefit from processing.

Hot fogging for bedbugs

The time of the disinsection is agreed in advance with the service representative. The price of the service ranges from 3-4 thousand rubles. for smoke treatment of a two-room apartment. You can order bullying online or by phone.

Further actions of a qualified specialist:

  1. Search for the main localization of bedbugs and their quantitative assessment.
  2. Selection of the optimal drug, dosage calculation.
  3. Bringing the pesticide to the desired consistency and refueling the fog generator.
  4. Checking the premises. The contractor must make sure that there is no air circulation in the apartment, the ventilation duct is closed. Fire alarm sensors are disabled during processing.
  5. Filling the housing with fog. The process itself is not long - the device intensively generates gas, the cloud quickly covers the entire room.

Gas cloud in the room

It is advisable to additionally send water vapor from the pesticide to the pest habitat (cracks, wallpaper joints, furniture sheathing). When the room is completely covered by a toxic cloud, you can leave the apartment for 1.5-2 hours.

Upon returning, all windows should be opened, the duration of ventilation is at least 2 hours.

How to handle with cold fog with your own hands

First of all, it is necessary to dilute the insecticide in accordance with the instructions and pour it into the generator reservoir. After that, the device must be turned on and the room must be carefully processed, directing the flow of fog onto the walls, floor, ceiling, baseboards and other surfaces. At the end of the procedure, the room should be completely filled with gas.

When the fog has completely settled, the room must be well ventilated and wet cleaned in it. There is no need to wipe the corners and the floor behind the furniture, this will destroy the surviving individuals. All clothes left in the closets should be washed immediately and the dishes should be washed thoroughly.

Cold fog from bedbugs

If the insecticide has a prolonged effect, one treatment is sufficient. In all other cases, the procedure must be repeated.

In order for the processing to take place without negative consequences, you need to observe safety precautions:

  1. Use a respirator, gloves, goggles, thick clothing. All parts of the body must be covered.
  2. Before turning on the device, all people and animals must be removed from the room. Aquariums and terrariums must be removed.
  3. If you feel unwell, you should immediately contact a specialist.

Important! Failure to comply with safety precautions when using powerful insecticides can lead to intoxication, respiratory tract damage and a severe allergic reaction.

How to choose an aerosol generator

With the help of aerosol equipment, high quality processing and disinfection can be performed. However, even having the most expensive device from one of the best world brands, you may not get the expected result. It turns out that the power of the equipment turns out to be insufficient, and sometimes, and vice versa, too powerful a tool fell into the hands.

To begin with, aerosol generators come in two main types:

  1. "Hot Mist" thermomechanical such as: AR35E, BW-30, B.F.150 Principle of operation: Working solution is injected into the hot gas stream. Due to the high temperature of the gas, the liquid instantly evaporates. The contact of the gas with the relatively cold air at the outlet leads to condensation of moisture in the form of droplets of 5-35 microns. A cloud or so-called fog is formed ..

2. "Cold fog"powered by electricity, such as SMB 100 (SM BURE), ATOMER, ULV Tornado 10, U60-PRO Work with the drug without heating it The drive motor draws in air and turns on a special compressor. The working solution in the tank is mixed with air. The solution is influenced by aerodynamic force and surface tension, as a result of which the smallest particles of the working solution are sprayed in the form of droplets from 10 - 80 microns.

The choice of generator must be carefully considered.

1. It is necessary to find out what types of processing, what, to what extent you need, and only after that determine which generator is best suited.

Pros and cons of the method

Cold fog bug killing technology has the following advantages:

  1. Long-term stay of the suspension in the air, which increases the toxicity of insecticides for bedbugs.
  2. Due to the fact that the steam jet is released under high pressure, the insecticide even gets into the space between the wall and the wallpaper, as well as behind the skirting boards. This allows you to kill not only bedbugs, but also cockroaches, fleas.
  3. Insects have already adapted to most of the aerosols tested over the years. That is why the effect of expensive products often leaves much to be desired. Modern insecticides are poured into the cold fog generator, which paralyze the insect's nervous system, leaving it no chance of survival.
  4. The method eliminates not only adults, but also larvae.
  5. Subject to the processing technology, the cold fog is not toxic to humans and pets.
  6. After disinfestation, there is no smell of pesticides.

The main disadvantage of cold fog is its high cost. But you can forget about this drawback by evaluating the effectiveness of the method. In 99% of cases, just one treatment is enough to forget about parasites for a long time.

Specifications

In the characteristics of the device, you can also trace the differences from conventional humidifiers. First of all, this is power. For an apartment or a small house, a 700-1000 W device is enough. But if we are talking about large studios, venues or pavilions, then the power should be about 1200-1500 watts. This indicator also implies productivity, which is 250-300 m 2 / min. That is, it is the volume of steam generation and delivery. Sometimes manufacturers calculate this value in "cubes".In this case, the average performance will be 50-70 m 3 / min. As for the characteristics of power supply, then 220 V is quite enough to serve a household ultrasonic humidifier. A fog generator from the professional segment, however, can also be powered from a three-phase 380 V. These are industrial installations, which, moreover, are large in size.

Testimonials

Alisa, Evpatoria: “I have my own business - a small but beautiful hotel with 10 rooms. I always kept an eye on the cleanliness, but suddenly there were bugs, which turned out to be quite difficult to get rid of. The guests began to write bad reviews, people refused to check in. They called a special service, they treated all the premises with a cold fog. Now we remember that time as a nightmare. It's good that the hotel's reputation is no longer threatened. "

Evgeny, Moscow: “I started hunting bedbugs myself. I read on the Internet about the cold fog treatment method, took a generator from a friend and poured an insecticide into it. The procedure was successful, no more insects appeared.

Margarita, Tver. Because of bedbugs, the whole family could not sleep well. Tried using aerosol and chalk but nothing worked. For a long time they could not decide on disinfestation with cold fog, fearing that it could be dangerous to health. But in the end, everything went quickly and without consequences. The insects completely disappeared, but just in case they did a second treatment, as the experts advised. "

Cold fog is a modern and effective way to get rid of bed bugs. A generator designed for domestic needs is available on the market, so you can process it yourself, subject to technology, this procedure is effective and completely safe.

Method effectiveness

Hot fog killing bedbugs gives a good result if several conditions are met:


Hot fog

  1. The treatment is carried out by professionals using the most effective insecticides and their appropriate concentration.
  2. At the end of the work, all recommendations of exterminators should be strictly adhered to.
  3. The room should be closed for exactly as long as necessary for the insecticides to completely settle. Most often, the process lasts from 5 to 10 hours.
  4. It is possible to expose the room to airing only 2-3 hours after the gas cloud settles. How quickly hot fog dissipates depends on the chemicals chosen.
  5. Carrying out wet cleaning after disinsection is provided in 10-14 days to ensure the safety of the insecticidal film. On the first day, only those surfaces with which the inhabitants of the house are in constant contact are treated with soap or soda solution.

On a note!

If, before contacting the sanitary service, there were independent attempts to eliminate bedbugs or disinfestation was already carried out by another company, these facts must be reported to the manager or exterminator. As a result of unsuccessful baiting, bed bugs could develop resistance to a number of chemicals. Awareness of employees of a specialized service will allow them to choose effective means that will destroy adapted insects.

Feedback

When the bugs started up in the sofa, without hesitation, I turned to the sanitary service - I wanted to quickly get rid of the nasty pests and forget about their existence. I was offered a choice of cold and hot fog from bedbugs, but for some reason the latter inspired me more confidence. The processing of the apartment took just over an hour. It took much more time to prepare for the arrival of exterminators: he took off carpets, moved furniture. For the duration of the disinfestation, I was given a protective suit and a respirator, so I could freely observe the process. The technology was not called hot fog for nothing, and this is how it all looked.At the end of the work, an employee of the sanitary service conducted a detailed briefing and warned that it was impossible to ventilate the apartment earlier than 8 hours later. They had cases when people immediately after the departure of the brigade began to open the windows, and then they also wondered why the bugs had not died. I did everything in strict accordance with the recommendations of the exterminator and the result was satisfied. After the treatment, all the parasites disappeared and for over a year I have not seen them.

Step-by-step instructions for the procedure

In order to independently and efficiently carry out the procedure for the destruction of insects and avoid possible negative consequences, it is recommended to follow the algorithm of actions given below, which does not actually differ from the one used for treatment using conventional spraying with toxic substances:

  1. All people must leave the premises initially.that are not involved in the processing.
  2. The selected insecticide is diluted with plain water in proportions, which are indicated in the instructions for it.
  3. Prepared and diluted concentrate is carefully poured into a special tank of the generator.
  4. Previously, furniture and all objects in the room should be brought in such a condition that they can be easily processed. In particular, it is imperative to remove the mattresses from the beds, and place cabinets and other overall furniture so that you can quickly access their back walls.
  5. Children's toys, electronic household appliances, utensils and other objects that are not supposed to be processed must be securely wrapped in plastic wrap or packed in bags. However, this is allowed only if there is confidence that insects, as well as their eggs or larvae, cannot be in them. Otherwise, the entire procedure will not have the desired effect, since protection will be provided to a part of the population, after which it will be able to breed again and spread throughout the apartment.
  6. The generator is connected to the home power grid.
  7. Before starting treatment, you will need to wear a gas mask or respiratory mask, disposable rubber gloves, a hat and protective clothing. It is best to equip yourself in such a way that there are as few open spaces as possible on the body.
  8. Having transferred the device to the operating mode, it is necessary to direct the jets of fog to the pieces of furniture, pulled out mattresses, baseboards and all existing cracks and loopholes in which insects can hide.
  9. After that, all wall surfaces are processed.because insects and their eggs may be behind the wallpaper.
  10. After processing all objects and surfaces, cold fog should be sprayed liberally into free space, changing direction from time to time.
  11. After completing the procedure, you must leave the room for a certain period, which is determined by the characteristics of the selected insecticide. Usually it is no more than 3-4 hours, but many experts recommend not visiting the treated apartment for several days, if possible.
  12. When returning to the treated room, it will be necessary to carry out wet cleaning, thoroughly wash all the dishes with a special detergent, wash things from the cabinets at high temperatures. It is not recommended to wash the crevices and back surfaces of the furniture, as the sediment deposited on them will provide protection from insects, preventing their recurrence.
  13. After a few weeks, it is recommended to repeat the procedure, since not all toxic substances can have any effect on the eggs of the pests, even with direct contact. Testing cold mist spraying will kill a new generation of insects, which will definitely prevent their return.

If, after the treatment, a person experiences any malaise, an allergic reaction or other side effects, it is recommended to contact a specialist for professional medical care.

Minor disadvantages of hot fog

They are the high cost of special equipment, the mandatory presence of special protective clothing, and a sufficient amount of knowledge about working with chemicals. Only such an arsenal, in conjunction with strict adherence to the instructions for operating the generator, will allow for correct, safe and effective processing, which will bring the optimal result of complete getting rid of bed bugs.

The habitat of bedbugs is shown in the diagram:


Also, the disadvantages include the prolonged time of the chemical procedure, the toxic effect of which must be in the air for at least 4-6 hours. And then you need to thoroughly ventilate the room for 120 -180 minutes, for the complete weathering of harmful substances.

Thus, all stages of treatment with hot chemistry are stretched almost for the whole day, which is completely incomparable with the reduced time of other methods for destroying bedbugs, in particular, using conventional aerosols.
